If you have never heard of the Yamaha DX7, you have missed a very important chapter in synthesizer history.
The DX7 is definitely one of the most influential digital synths ever produced. It’s also one of the most used synthesizers ever. When the DX7 was originally introduced in 1983, Yamaha quickly found out that they had produced something beyond their wildest expectations: they simply couldn’t make enough of them. I believe that some 160 000 of these synthesizers were produced between 1983 and 1987.
